The world has ended. Zombies wander the land. You design a car with spikes on the front to try to drive through zombies in your way. Your 1,200 kg vehicle is driving at 40 m/s and
collides with a 100 kg zombie (it's a big onel) that is stationary, and the zombie sticks to your
spiked front end. How fast will you and the zombie be moving after the collision?

In order to place a satellite into orbit, it requires enough fuel to supply the necessary mechanical energy. into what types of mechanical energy does the fuel get transformed?

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
